In the field of flow control, the selection of a wall-mounted ultrasonic flow sensor directly affects system accuracy and stability. As a professional instrumentation manufacturer, Xi'an Shenghongchuang provides you with an in-depth analysis of the technical differences between the two popular models TDS-100H and FR-500H, covering parameter comparisons of more than 10 competing products such as TDS-100P and SK-TUF-2000H, helping technical evaluators quickly match industrial application requirements.

I. Definition and Core Advantages of Wall-Mounted Ultrasonic Flow Sensors

A wall-mounted ultrasonic flow sensor is a non-contact instrument that measures fluid flow through the ultrasonic transit-time method. Its core advantages lie in convenient installation, low maintenance cost, and suitability for corrosive media. The TDS-100H series developed by Xi'an Shenghongchuang based on an ISO 17025-certified laboratory adopts multi-pulse coding technology, improving measurement accuracy to ±0.5%, which is significantly better than traditional mechanical flowmeters. The FR-500H model, through its adaptive signal processing algorithm, can still maintain ±1% stability in complex fluids containing bubbles or particles. This feature offers unique value in industries such as wastewater treatment and chemicals.

II. Key Technical Comparison Between TDS-100H and FR-500H

Compared with similar products on the market such as SK-TUF-2000H or ZC-TUF-2, TDS-100H offers a wider turndown ratio (100:1) within the DN50-DN600 pipe diameter range, while FR-500H, with its unique self-cleaning probe design, can reduce the impact of fouling by 80% during long-term operation. Xi'an Shenghongchuang's test data show that at a petrochemical project site, FR-500H still maintained 99.2% reading consistency after 2000 hours of continuous operation, a figure far exceeding competing products such as FUGI-1881X.

III. Selection Decision Tree and Industry Application Matching

For technical evaluators, we recommend selecting through the following decision path: first, confirm the medium characteristics—clean fluids should preferably use the TDS-100H series to obtain higher accuracy, while media containing particles or bubbles should use FR-500H; second, examine the installation environment, and for highly corrosive scenarios such as chemical applications, the JY-TUFH model with a 316L stainless steel housing is recommended; finally, evaluate data interface requirements, as both SC-TUF-2000H and DX-TUF-2000H support the Modbus RTU protocol and can be seamlessly connected with PLC systems. Xi'an Shenghongchuang's engineering case database shows that ZRN-100H achieved an annual comprehensive error of ±0.8% in centralized heating systems, making it the preferred solution for regional energy metering projects.

IV. After-Sales Technical Support and Customized Services

As a national high-tech enterprise, Xi'an Shenghongchuang provides full-cycle services from selection consultation to on-site commissioning. Our technical team can expand the functions of standard models such as TDS-100P according to customers' special requirements, such as adding 4-20mA+HART output or customizing explosion-proof housings. Compared with similar suppliers at home and abroad, we promise 48-hour emergency response and lifetime free calibration services, which has enabled products such as DX-TUF-2000H to gain continuous procurement in key fields such as metallurgy and pharmaceuticals. The anti-static version of FR-500H recently customized for a semiconductor factory successfully solved the flow monitoring challenge in cleanrooms, and the project won the 2023 China Automation Innovative Application Award.
